Gaskets Seet


PTFE Sheet Gasket Material Virgin, Mechanical and Expanded PTFE grades The perfect material for Food (FDA) applications. Chemical Compatibility 0-14 PH Good for Temperatures to 450F


Ameri-lon a new family of products using a new hybrid material, Ameri-lon is the result of years of experience in producing PTFE materials.  It is designed for a wide range of demanding industrial requirements including gasket and bearing applications.  Ameri-lon is filled PTFE, uniquely combining the properties of PTFE and Aramid materials.  Aramid enhances the physical properties of PTFE and results in a superior gasket material.  Ameri-lon shows less cold flow and greater sealing ability than other filled PTFE materials (PTFE) or Fluorocarbons.  It maintains the chemical attack resistance and the temperature range of PTFE. Product equivalents to Gylon :  Ameri-lon 9810 = Gylon 3504 , Ameri-lon 9820 = Gylon 3510, Ameri-lon 9840 = Gylon 3500, Ameri-lon Expanded PTFE = Gylon 3450/3545, Amerilon ® PTFE = Gylon Chemrex 3570 * * This is to be used as a general guide only. All applications should be considered individually

Gaskets made from PTFE resin or Generic PTFE

Virgin* Mechanical Grade*Expanded PTFE* Gaskets cut from Virgin or mechanical grade material,posses all of the great aspects of PTFE like chemical compatability and a 450-500F temperature range, but require torque to seal.  If that torque is not possible or if flange faces are worn or pitted, Expanded PTFE , gaskets are the answer.

Expansion joints made with PTFE resin Bellows

Allow Your Chemical System To Flex When It Has To. Using PTFE Expansion Joints Saves Wear On Your System And Protects From Pipe Strain. Ideal When You Have To Deal With Chemicals.

Is all PTFE the same?

The most common PTFE resin came from Dupont in 1945. Today the name Teflon is owned by The Chemours Company. Chemours™ and the Chemours Logo are trademarks or registered trademarks of The Chemours Company. Teflon™ is a trademark of The Chemours Company FC, LLC. Access and use of the Teflon™ brand require a trademark license from Chemours.  There are now multiple competing PTFE products from Germany, Japan, India, and China, but are they true equals? To the naked eye, they will all look similar enough, but if you operate a laser to cut materials as we do, it does not take long to realize that not all PTFE materials are the same. To cut the identical part it may take more or less wattage/speed/frequency to get similar results.  Clearly, some PTFE is made with inferior fillers. If you want the best, it’s always best to specify Teflon™.
